示例1:
void
WorkspacesView::_CleanupParentClipping()
{
// Restore the previous parent state. NOTE: This relies on views
// being detached in exactly the opposite order as them being
// attached. Otherwise we would mess up states if a sibbling view did
// the same thing we did in AttachedToWindow()...
fParentWhichDrawsOnChildren->PopState();
}示例2: DrawStatusBar
void wxStatusBarBeOS::DrawStatusBar()
{
int i=0;
